Shenandoah Valley in the context of "Rockfish Gap"

Virginia, officially the Commonwealth of Virginia, is a state in the Southeastern and Mid-Atlantic regions of the United States between the Atlantic Coast and the Appalachian Mountains. The state's capital is Richmond and its most populous city is Virginia Beach. Its most populous subdivision is Fairfax County, part of Northern Virginia, where slightly over a third of Virginia's population of more than 8.8 million live.

Eastern Virginia is part of the Atlantic Plain, and the Middle Peninsula forms the mouth of the Chesapeake Bay. Central Virginia lies predominantly in the Piedmont, the foothill region of the Blue Ridge Mountains, which cross the western and southwestern parts of the state. The fertile Shenandoah Valley fosters the state's most productive agricultural counties, while the economy in Northern Virginia is driven by technology companies and U.S. federal government agencies. Hampton Roads is also the site of the region's main seaport and Naval Station Norfolk, the world's largest naval base.

Bluestone is a cultural or commercial name for a number of natural dimension or building stone varieties, including:

• basalt in Victoria, Australia, and in New Zealand
• dolerites in Tasmania, Australia; and in Britain (including Stonehenge)
• feldspathic sandstone in the US and Canada
• limestone in the Shenandoah Valley in the US, from the Hainaut quarries in Soignies, Belgium, and from quarries in County Carlow, County Galway and County Kilkenny in Ireland
• slate in South Australia

It is unrelated to human-made blue brick.

The eastern panhandle is one of the two panhandles in the U.S. state of West Virginia; the other is the northern panhandle. It is a small stretch of territory in the northeast of the state, bordering Maryland and Virginia. Some sources and regional associations only identify the eastern panhandle as being composed of Morgan, Berkeley, and Jefferson Counties. Berkeley and Jefferson Counties are geographically located in the Shenandoah Valley. West Virginia is the only U.S. state with two panhandles.

The Hagerstown–Martinsburg metropolitan area, officially designated by the United States Office of Management and Budget (OMB) as Hagerstown–Martinsburg, Maryland–West Virginia Metropolitan Statistical Area (MSA), constitutes the primary cities of Hagerstown, Maryland; Martinsburg, West Virginia; and surrounding areas in three counties: Washington County, Maryland; Berkeley County, West Virginia; and Morgan County, West Virginia. The metro area lies mainly within the rich, fertile Cumberland and Shenandoah Valleys and is approximately a 60–90 minute drive from Washington, D.C.; Baltimore, Maryland; and Harrisburg, Pennsylvania; Hagerstown is approximately 75 miles (121 km) driving distance from all three cities. The population of the metropolitan area as of 2008 is 263,753.

U.S. Route 522 (US 522) is a spur route of US 22 in the states of Virginia, West Virginia, Maryland, and Pennsylvania. The U.S. Highway travels in a north-south direction, and runs 308.59 miles (496.63 km) from US 60 near Powhatan, Virginia, to its northern terminus at US 11 and US 15 near Selinsgrove, Pennsylvania. US 522 serves many small cities and towns in the Piedmont, Blue Ridge Mountains, and northern Shenandoah Valley of Virginia. The highway serves the Virginia communities of Goochland, Mineral, Culpeper, the town of Washington, and Front Royal and the independent city of Winchester. US 522 then follows the Ridge-and-Valley Appalachians north and then east through the Eastern Panhandle of West Virginia, a 2-mile-wide (3.2 km) stretch of Western Maryland, and South Central Pennsylvania to its terminus in the Susquehanna Valley. The highway serves Berkeley Springs, West Virginia; Hancock, Maryland; and the Pennsylvania communities of McConnellsburg, Mount Union, Lewistown, and Middleburg.

The Battle of Gettysburg (locally /ˈɡɛtɪsbɜːrɡ/ ) was a three-day battle in the American Civil War, which was fought between the Union and Confederate armies between July 1 and July 3, 1863, in and around Gettysburg, Pennsylvania. The battle, won by the Union, is widely considered the Civil War's turning point, leading to an ultimate victory of the Union and the preservation of the nation. The Battle of Gettysburg was the bloodiest battle of both the Civil War and of any battle in American military history, claiming over 50,000 combined casualties. Union Major General George Meade's Army of the Potomac defeated attacks by Confederate General Robert E. Lee's Army of Northern Virginia, halting Lee's invasion of the North and forcing his retreat.

After his success in the Battle of Chancellorsville in Spotsylvania County, Virginia in May 1863, Lee led his Confederate forces through Shenandoah Valley to begin the Gettysburg campaign, his second attempt to invade the North. With Lee's army in high spirits, he intended to shift the focus of the summer campaign from war-ravaged Northern Virginia in the hopes of penetrating as far as Harrisburg or Philadelphia, which he hoped would convince northern politicians to end the war. President Abraham Lincoln initially prodded Major General Joseph Hooker into pursuing Lee, then relieved him of command just three days before the Battle of Gettysburg commenced, replacing him with Meade.

Berkeley County is located in the Shenandoah Valley in the eastern panhandle region of West Virginia in the United States. The county is part of the Hagerstown–Martinsburg metropolitan area. As of the 2020 census, the county population was 122,076, making it the second-most populous of West Virginia's 55 counties, behind Kanawha County. The City of Martinsburg is the county seat.
